直立式岸壁折角处泊位长度优化研究

Optimizationon berth length for corner of vertical quay wall

随着船舶大型化的发展,运用《海港总平面设计规范》中直立式岸壁折角处船长系数计算大型码头泊位长度时,易造成一定的岸线资源浪费。在原规范制定思路的基础上,分析和推导了在不同角度、不同船型、不同靠泊状态下直立式岸壁折角处船船(岸)间距与船舶尺度的关系和规律;细化了折角处不对称靠泊情况下的船长系数取值。同时,结合实际操船经验对大型船舶在不同折角情况下的船长系数进行优化和修正,在保证船舶操船安全的前提下,适度减少折角处泊位的富裕长度,达到节约岸线资源的目的。

With the development of the large-scale vessel,the corner berth length of vertical quay wall for large-scale terminals will usually cause more occupation of shoreline, when calculating with the vessellength parameters which is determined by the D esign C ode of G eneral Layout for Sea Port. Based on the idea of original train of thought, the relations and regular pattern are analyzed and derived among the distance between ships or ship and the quay wall, ship dimension, in different angles, ship types and berthing circumstances. In addition, the paper presents vessel length factors in the shoreline corner in the case of asymmetric berthing. Meanwhile, vessel length parameters are optimized and fixed in different shoreline corners,on the basis of maneuverability experience of large-scale vessel. The purpose of this study is to economize the resource of shoreline by moderately reducing the surplus berth length at the shoreline corner,which is in the premise of ensuring the safety of the maneuverability.
